IMPROVEMENT IN ELECTRIC LININGS FOR SAFES.

Specication forming part of Letters Patent No. 120,874, dated November14, 1871.

To all whom it may concern:

Be it known that we, EDWIN Hom/nts, of Brooklyn, in the county of Kingsand State of New York, and HENRY C. EOOME, of Jersey City, in the countyof Hudson and State of New Jersey, have invented a new and usefulImprovement in the Application of Electric Lining to Vaults, Safes, andother structures 5 and we do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification.

Figure l represents a sectional elevation provided with our improvedelectric exterior casing. Fig. 2 is a horizontal section of the same..Fig. 3 is a detail section of part of the screen.

Similar letters of reference indicate corresponding parts.

This invention relates to an improved method of applying electric-alarmapparatus to saf'es, vaults, and other structures, with the view togreater efficiency of action and simpler mode of application.

The method heretofore employed haskbeen to apply a lining connected withthe electric appa ratus directly to the inside of the safe or vaults.

' Whenever such a safe'A or vault is attacked by burglars it is injuredor `-destroyed before the linin gis reached and the alarm given. Toremedy this defect we build around the structure A to be guarded anexterior case, to which the lining` B, which may consist either ofmetallic sheets or a network of wires, is applied, and which shallconstitute an exterior electrical burglar-proof safe of itself, so thatif any attempt be made to enter by cutting, drilling, or breakingthrough an alarm will be sounded before the structureguarded A is itselfreached. This exterior inclosure B is provided with a door, a, through,which access may be gained to the door of the structure guarded, andsaid door being provided with the usual springs to break or establishelectrical contact in the act of opening or closing. If any particularportion of a safe or vault is considered especially liable to theassaults of burglars and the remainder thought to be safe, we apply tothat particular portion a section of this exterior case, withoutinclosing the whole.. We prefer to build this outer inclosure of wood orpapier-mache b, and apply the electrical lining c to its interiorsurface. To protect'the lining from injury by contact with the sides ofthe safe or vault we either interpose a thin partition, d, of wood,papier-mache, or straw-board between the two, or set the lining a shortdistance from the wall of such safe or vault, to obtain an intermediateair-space. rllhe lining of the door should always be so protected byhaving the interior partition fastened to the outer door, thus inclosingthe lining between two protecting surfaces. The lining may be applieddirectly to the exterior surface of the safe proper and be covered bythe protecting surface. The electric lining may, however, also beapplied to the exterior' body of the safe without the use of an outerprotection.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. A safe or vault provided with an electricouter lining surrounding or covering it Wholly or in part, and insulatedtherefrom, and protected, substantially as herein shown and specified.`2. The exterior inclosure B, made of the paris, I; and c, substantiallyas herein shown and described, to be applied to a safe or vault, in themanner specified.
